A woman came to the Prophet (ﷺ) and said: I gave a slave girl to my mother, but she died and left the salve-girl. He said: Your reward became certain for you, and she (the slave-girl) returned to you as inheritance. She said: She died and one month's fast was due from her. He (the narrator) then mentioned the tradition similar to the one mentioned by 'Amr b. 'Awn.
